需要得到良好的bash程序員一些幫助

Question

我有以下

#!/bin/bash 
function labels2() { 
    awk ' 
    /[0-9]/{ 
    print substr($3,length($3)-11), $3 
    }' $@ | /bin/sort -u | awk '{print "BUILD: " NR, $2}' 
} 

function labels() { 
    awk ' 
    /[0-9]/{ 
    BL[$3] = substr($3,length($3)-11) 
    } 
    END { 
    asort(BL) 
    for (i in BL) { 
     print i, BL[i] 
    } 
    }' $@ 
} 


labels $@ 

for a in $@ 
do 
    labels $@ | gawk ' 
    /BUILD:/ { 
    BUILD[$2] = $3 
    BUILDCNT ++ 
    next 
    } 
    /[0-9]/ { 
    DATEd[$3] = $1 
    TIMEd[$3] = $2 
    MODULESd[$3] = $4 
    CASESd[$3] = $5 
    FAILEDd[$3] = $6 
    COVERd[$3] = $7 
    LOCd[$3] = $8 
    } 
    END { 
    SUBSYSTEM=substr(FILENAME, 1, length(FILENAME)-7) 
    LABEL= "\"" toupper(SUBSYSTEM) "\""

這個腳本，它提供了以下輸出時「feeded」與當前的文本文件gps.txt

2011-01-22 22:12 P16A22_110114072915 22 1312 75 13.55 1399 
_ 




1 110114072915 
#{ 
"buildnames": { 
     "label": "buildnames", 
     "data": [ 
     ] 
     } 
}; 
#{ 
"subsystem": "GPS", 
    "date": { 
     "label": "GPS", 
     "data": [ 
      [0, "1"], 
     ] 
    }, 
     "time" : { 
     "label": "GPS", 
     "data": [ 
      [0, "110114072915"], 
     ] 
    }, 
     "modules" : { 
     "label": "GPS", 
     "data": [ 
     ] 
    }, 
     "cases" : { 
     "label": "GPS", 
     "data": [ 
     ] 
    }, 
     "failed" : { 
     "label": "GPS", 
     "data": [ 
     ] 
    }, 
     "cover" : { 
     "label": "GPS", 
     "data": [ 
     ] 
    }, 
     "loc" : { 
     "label": "GPS", 
     "data": [ 
     ] 
    } 
    }; 

我想要的樣子是這樣的

#{ 
"buildnames": { 
     "label": "buildnames", 
     "data": [[0,"BUILD: 1 P16A22_110114072915"] 
     ] 
     } 
}; 
#{ 
"subsystem": "GPS", 
    "date": { 
     "label": "GPS", 
     "data": [ 
      [0, "2011-01-22"], 
     ] 
    }, 
     "time" : { 
     "label": "GPS", 
     "data": [ 
      [0, "22:12"], 
     ] 
    }, 
     "modules" : { 
     "label": "GPS", 
     "data": [[0,22] 
     ] 
    }, 
     "cases" : { 
     "label": "GPS", 
     "data": [[0,1312] 
     ] 
    }, 
     "failed" : { 
     "label": "GPS", 
     "data": [[0,75] 
     ] 
    }, 
     "cover" : { 
     "label": "GPS", 
     "data": [[0,13.55] 
     ] 
    }, 
     "loc" : { 
     "label": "GPS", 
     "data": [[0,1399] 
     ] 
    } 
    }; 

所以把這個問題分解成子問題

1. 爲什麼行1 110114072915在頂部，我該如何刪除它？

2. 我如何使用功能labels2()，使得從它(BUILD: 1 P16A22_110114072915)輸出會在buildnames這樣

   "buildnames": { 
       "label": "buildnames", 
       "data": [[0,"**BUILD: 1 P16A22_110114072915**"] 
       ] 
       } 
   

3. 這是最後一個問題：爲什麼不這項工作MODULESd[$3] = $4，CASESd[$3] = $5等......當我循環並打印出來時，它就變成了什麼。

請注意這裏，該文本文件gps.txt將不斷擴大，因此，在未來它可能是50行，這將是一件好事，如果sollution仍然會工作=）

我知道這成了很多文本，我爲此道歉，而且我可能無法就所有問題得到答案，但是如果您可能有一個想法如何實現其中的任何一個，我會更加高興，因爲我目前被卡住了並不知道如何去做我想做的事情。不幸的是，這種做法是我唯一的選擇。

感謝你的努力=）

Answer 1

這是所有基於心理過程 - 我還沒有真正運行的命令呢。這將有助於看到該文本文件的示例

1）爲什麼行1 110114072915在頂部，我該如何刪除它？

它看起來像循環打印信息之前的光禿labels $@調用。擺脫這一點。

2）您可能應該將該邏輯遷移到底部的awk命令中。關聯數組分配可以在第二個塊/[0-9]/中完成，而END邏輯可以直接放入大腳本的END塊中。

3）文本文件每行有8個字段嗎？作爲調試，使用類似print NF > "/dev/stderr";的東西來確保在設置變量時確實有8個字段。

Answer 2

1）爲什麼行1 110114072915在頂部，我該如何刪除它？

Foo Bah正確回答了這個問題。

這看起來我錯了：

for a in $@ 
do 
labels $@ | gawk ' 

你爲什麼要遍歷所有的ARGS，然後運行labels $@不labels $a？

2）如何可以使用函數標籤2（）

我將運行功能並分配輸出到AWK變量：

labels $@ | gawk -v "bnames=\"$(labels $a)\"" ' 

然後使用在該變量awk腳本：

print "  \"data\": [", bnames 

3）這是最後一個問題：爲什麼不工作

我不知道，但你永遠不會知道，除非你將問題分解成小塊並自行調試。如果你寫了一百行的awk腳本，並且它不起作用，答案是嘗試讓一個簡單的十行版本起作用，然後逐漸增大它並檢查每個部分的工作情況。
